Savennières hills form a series of oblique folds sunk under the south-west border of the Parisan basin and the oriental edge of the Armorican chain. They are schistose-sandstone formations with some phtanites and volcanic stones ( spilite, rhyolite) from the primary era covered with wind sands from the quaternary era.

The arable land is, generally speaking, not very deep (about 50 cm) on a bed of sturdy sandstone schist. It is well drained , with a silt and rocks texture. Excessive water, which could asphyxiate the roots as in heavy or agrillaceous soils, never occurs. Consequently the roots can reach very deep areas, penetrating through vertical faults, searching for water and the mineral elements essential to the growth of the vine. In summer, this protects the vine from suffering drought.

The characteristics of the Savennières soil endow the vines with an extremely high precocity potential. The earlier a vine can develop its leaves, the longer it will be able to benefit from the sun during the summer and thus reach perfect ripeness for the harvest.
